ABSTRACT:
In a multi-cavity molding apparatus that includes a cavity part having a plurality of cavity sections that is combined with a core part having a plurality of cores to define a plurality of mold cavities therebetween, and a plurality of locking rings respectively disposed around a plurality of the cores for engagement with respective cavity sections when the core part is combined with the cavity part, a cavity shield is attached to the cavity part to prevent molded products ejected from the mold cavities from entering spaces between the cavity sections of the cavity part and a core shield is attached to the core part to help prevent the ejected products from entering spaces between the cores of the core part. The cavity shield and the core shield thereby respectively limit obstruction by the cavity part and the core part of removal of the ejected products from the space between the cavity past and the core part. The core shield includes more than the ejection means.
